central partof the hull of a vessel and showing my improved ropellingand steering apparatus applied to oth sides thereof and the motors bywhich the apparatus is operated, Fig. 6 aplan view ofthe constructionshown in Fig. 5, and ,'-Figs 7 and 8 side and end views respectivelyshowing my invention applied to an airship.v

In the practice of my invention as shown in Figs. 1f and 2 of thedrawings, I provide'a motor or power-device 70 made in the form of arotary pump or engine, and comprising a casing 70d consisting oi twoapproximately cylindrical members 5 and 6 formed on the sides of saidpart.

ey for transmitting power s used as a pump, ltate said shaft when thedevice is -used as a when the device,

scribed 'in the application hereinbefore" Ireferred to. f

prise a hub and a series of arms 17 and cor.- responding sockets 18, andthe arms 17 of lone wheellit in the corresponding sockets 18 of theother wheel, and when one of said wheels is rotated the other will becorrespondingly rotated as will be readily understood. rThis rotationmay be 4caused by the shaft 11 to which power 'may be applied when thedevice is maybe caused by a blast of steam from the inlet 7 when thedevice is used as a motor.

The wheels thereof are provided with radial slotslQ in which are placedradially movable`piston blades 2O provided at their inner ends or edgeswith lateral lugs 21, and the opposite sides 9 of the `casing 70a areprovide with circular grooves 22 concentric with the sepa-y rate partsof said casing but eccentric tothe shafts liand 12, and theoppositesides of 'the casing 7()a are provided with circular bosses 30in which said grooves are formed,

having an inlet f 7 at the point where the `two members-fare other partof said 'casing and', the endsl thereof lit inl socket bosses 12?ymotor, these features of construction beingl not shown herein, but beingshown and dey `used* as a pump, or itI The shaft l1 may be provided'witha pul- Or to receive a belt to ro- The shafts l1 and 12 are providedwith interlocking wheels 15 andl which com 15 and 16 and the arms 17 andas the wheels 15 and -16 revolve therlugs.

i water in the manner of other devices of this class and according towhether the device isl used as a motor or as a pump. 4

When the device is used as a pumpthe rotation of the shaft 11 in thedirection of the arrow causes the rotation of the wheel. 15,v

and the wheel 15 turns thewheel .16 and causes a suction at the inlet 7and the Water flows in at said inlet 7 and out at the outlet8,.thepiston blades 20 operating to produce this result. When the.device 1s used as a motor and operated by steam the move- -ment ofthevvarious parts thereof will be the same, the steam entering throughthe inlet 7 and leaving at the outlet 8 thus forcing the wheels 15 and16 to revolve. lf it is desired to reverse the operation of the devicethe steam is admittedatS and dischar ed at7 as will be readilyunderstood, and t is may be done by any desired form of apparatus, or bythat shown and described in the application hereinbefore referred to.

In Figs. 8 andv 4 of the accompanying drawings I have shown at 7 0c thestern portion of the hull of a vessel and have also shown at 80 apropeller made according to ymy invention, and thispropeller is operatedby the motor device 70 hereinbefore described. The propeller 8O is madeinthe same manner as the motor with the following exceptions. Thecasing` 70a is placed in a horizontal position andthe outer or oppositesides theieofare removed as shown at 70b so as to expose the arms' 17land blades 20 of the wheels `15 and 16. In this use of the device thestern of the vessel is provided with a top bracket or support 37 and abottom bracket or support 39, and the bottom bracket or support isprovided w1th an extension 40 which forms a segmental track or way'onwhich a part of the propeller may rotate las. hereinafter described. Thepropeller 80 is `mounted between the brackets or supports v37 and 39,and the shaft-11 of the motor passes downwardly through the brack- 'etsor su ports 37 and 39 and through one side partof t 1e propeller and oneof the'wheels in the propeller, said wheels being the same as thewheels15 and 16. The shaft 11 passes through a sleeve 36 mounted in thebracket or support 37` and provided at its upper end with a head 36ahaving a segmental gear 44, and another sleeve- 38 is 11 below themotor. he motor 7 0*, supported inthe manner shown and described is in aplane above the hull of the vessel, and secured within or on the hull ofthe vessel is a support 37 a on which isl pivoted a segmental me auslaced on the shaft..

gear 43 which operates in connection with the gear 44, and the gear 43isprovided with an arm 42 `and a downwardly directed projection 46 throughwhich is passed a set screw 45 which operates in connection with thesupport 3 7a to hold the gear 43 in any desiredl position. Steam pipes-35- are connected with the inlet-7 andoutlet 8 of the motor, and one ofthese pipes serves to supvmotor 70 is also provided with side braces 34awhich are connected therewith and with the h ull of the vessel.A -Thatpart of the propeller 80 opposite that through which theshaft v11 passesis provided with an anti-friction wheel or roller 41 adapted to travelon the segmental track or'way40 and to serve as an anti-friction supportfor the propeller inthe operation thereof as hereinafter described. Thesleeve 36 is formed integral with the casing 70a of the propeller 80 orsecured thereto, and by means of the arm,42 of the gear 43 which servesas a tiller, the propeller 80 may be turned into different posi- I tionsas will be readily understood, and the tiller may be locked in anydesired position by the .screw 45 or by any vother preferred Intheconstruction shown in Figs. Sand 4, my improvement is supposed to beapplied to a small boat and the steering may be done by means of the arm42, but it will be understood that when the apparatus is applied tolarge vessels the tiller may be operatedgby a small motor or in anydesired way. lVith this construction, it will be apparenhvthat the boatmay be propelled, and by manipulatingthe tiller 'arm 42 of the propellermay be swung into different positions so as to change the direction orcourse of the vessel drawings Ihave shown my improvement applied to theopposite sides of. a oat, sa-id boat being preferably of the ferryboattype, or

lbeing provided with overhanging side decks,

and in this adaptation of thedinvention'the brackets or su ports 39having the segmental or ar-saped vmembers 40 are employed, andtwo of thecombined motors and propellers'are employed, inthe form of constructionshown', at eachside of the boat. rf-he motors 70 are placed 'above thedeck of the boat and. the propellers 8() below the deck. The shafts`'11of the motors pass downwardly through thepropellers the same as in theconstruction shown in Figs. 3 and 4, and said propellers'or the casingsthereof are provided with the sleeves 36, and the upper ends of thesesleeves are provided with steam steering motors 48 for the purpose ofturning the propellers 8O on the brackets or supports 3S), and thesesteam steering motors 48 are provided with pipes 53 which are incommunication with othersteam supply 'pipes ol which are connected withor communicate with a boiler 50, and the pipes 51 also connect with andoperate the motors .70 by means of the pipes 35 the same as in theconstruction shown in Figs. 3 and el. and the pipes 35 conmumicate withthe inlet and outlet 7 and S of the motors and said pipes are providedwith reversing valves 7a and 8a operated by a single valve rod S" asshown and described in the application hereinbefore referred to, butthis reversing mechanism may be of any desired construction.
